Abstract
Vertical Axis Turbines (VATs) are gaining traction as decentralized energy sources due to their simple design and suitability for various wind conditions. However, understanding VAT aerodynamics requires robust computational methods. This study compares the accuracy and efficiency of two meshing techniques (sliding mesh and overset mesh) for VAT simulations using OpenFOAM. Validation against experimental data confirms the capability of both methods to capture flow physics and predict turbine performance. The results suggest both techniques offer efficient and accurate VAT simulations, providing valuable tools for future VAT optimization and experimental validation.
